Summary: The study found that 0.1-0.5 wt% of multi-wall carbon nanotubes can prevent the auto-oxidation degradation of fluorosilicone rubber by scavenging alkyl radicals, showing antioxidant effect. Density functional theory calculations revealed that carbon nanotubes are an open-shell system capable of reacting with highly reactive radicals.

Summary: This study investigates the interface of polyetheretherketone (PEEK) with carbon nanotubes (CNTs) and graphene, revealing that the interface between graphene and polymers yields larger adsorption energies than CNTs. The adsorption energies decrease with increasing temperature, showing a slight dependence on the initial relative orientation between CNT substrates and the extended polymer chain.

Summary: An ultrafine carbon nanotube (CNT) is developed as a cathode catalyst for solid-state lithium-oxygen batteries (SSLOBs), improving the solid-solid contact issue and providing a superior specific capacity. The amorphous discharge products formed on the CNT surface and between the CNTs and solid electrolyte particles are found to reduce cell impedance and increase reactive sites. The growth morphology of Li2O2 and the conduction paths of amorphous (Li2O2)n cluster are also determined for the first time.

Summary: In this study, chitosan modified Fe pretreated biochar (CS-FBC) was tested for its effectiveness in removing ciprofloxacin (CIP) from an aqueous solution. The experiment showed that the adsorption impact was rapid, reaching 80% in the first 60 minutes. The kinetic model suggested that the adsorption process may be connected to chemical adsorption, and the adsorption rate could still be maintained after multiple experiments.

Summary: Metal-phthalocyanines are catalytically active materials widely used in energy conversion and storage fields. In this study, the electrocatalytic origins of cobalt-phthalocyanine molecular catalysts were elucidated using experimental and computational methods. The electronic properties were fine-tuned at the atomic level. The aminated cobalt phthalocyanine-based electrocatalysts showed high activity and selectivity in oxygen reduction and evolution reactions, and exhibited exceptional kinetic current density and cycling stability in Zn-air batteries.

Summary: In this study, the triboelectric performance of PDMS and MWCNT-PDMS based TENG is investigated using theoretical calculations and experimental verification. The influence of contact surface area on the open circuit voltage of TENGs is studied. The results demonstrate that increasing the contact area improves the open circuit voltage of TENGs, and the addition of MWCNTs significantly enhances the voltage output.

Summary: A series of Cu/Al doped nitrogen-containing carbon microspheres were synthesized using a simple one-pot hydrothermal method and employed as efficient adsorbents for the removal of oxytetracycline (OTC) contaminants from water. Cu/Al@NC-2 exhibited the highest adsorption capacity for OTC and maintained excellent removal efficiency even after five adsorption cycles. The thermodynamic analysis demonstrated the spontaneous endothermic nature of the adsorption process. This study highlights the potential of Cu/Al@NC-2 for antibiotic wastewater treatment.

Summary: This study investigated the adsorptive removal mechanism of three tetracycline antibiotics from aqueous solutions by zero-valent iron@biochar nanocomposites prepared using hazelnut shell as the carbon source. The experimental results showed that under optimized conditions, the nanocomposite exhibited high removal efficiencies of up to 95% for oxytetracycline and chlortetracycline, indicating potential applications in antibiotic removal.

Summary: In this study, the morphology evolution and electron transport pathway of (Li2O2)n on the surface of NCNTs were investigated. It was found that (Li2O2)n underwent a process of evolution from scattered small-sized clusters to filmlike and toroidal large clusters. The presence of pyridinic N3 and pyridinic N4 was effective in reducing the capacity loss caused by Li2O2 branches, which improved the deposition stability of (Li2O2)n. Additionally, (Li2O2)n with p-type semiconductor characteristics acted as a bridge between NCNTs for electron transfer.

Summary: Antibiotics, as an environmental concern, have gained widespread attention due to their dispersion, bioaccumulation, and resistance. Traditional wastewater treatment methods are not effective in completely removing antibiotics, hence adsorption and photocatalysis using carbon-based materials such as graphene, carbon nanotube, biochar, and hierarchical porous carbon have been proven to be promising in antibiotic removal. This review provides an overview of these carbonaceous materials, their applications, mechanisms, and future research needs.

Summary: The study reveals the three main stages of Li2O2 growth on the CNT surface and the positive correlation between dense deposition and the number of Li2O2 monomers. By regulating the CNT structure and preparing catalysts, the conversion of Li2O2 from an ordered state to an amorphous structure can be promoted to overcome the technical bottleneck of LOBs.

Summary: The interfacial behavior of associating species is crucial for both fundamental physics and industrial applications. This study investigates the adsorption behavior of a mixture of nanoparticles and polymer chains, representing asphaltene and resin molecules, onto an attractive surface. The results provide insights into the effects of various characteristics of these molecules on the adsorption amount and reveal the interplay between different driving forces.
